gtfs-viewer-processing

A tool to compute all the intermediate stops (geometry and time range) between each trips from a GTFS in order to emulate their travel

You can see the visualization of the results here

Install the environment with pyenv and poetry

pyenv local 3.10.7
poetry env use 3.10.7
poetry install

Configure parameters files

params.json

Each block are used to compute all the moving stops from the specified GTFS:

set the name of your gtfs without space ("study_area_name")
Copy paste your data into the 'input_data' (for example) directory ("input_data_dir")
Select the transport modes to compute in a list ("transport_modes")
Select the date filter mode: based on "calendar_dates.txt" or "calendar.text" ("date_mode")
Define the date to compute ("date")
Set if you want to build the "shapes.txt" file ("build_shape_id")
Set the interpolation nodes values: 100 = 1 nodes interpolated each 100 meters ("interpolation_threshold")
Set if you want to proceed data with multiprocessing mode. Good only if you have a lot of trips! ("multiprocess")

inputs_attrs.json

Copy paste the 'inputs_attrs.json' file into your data direction (ex: 'input_data') This file is used to map column types for each gtfs files

Run the data building

Let's go to compute your data

python db_run.py

You'll get 3 parquet files which can be use with TODO:

[study_area_name]_moving_stops.parq:

Contains all the stops interpolated

[study_area_name]_base_stops_data.parq

On going.... [TODO]

[study_area_name]_base_lines_data.parq
